When I see a patient for the first time and he is shaved, I start off by saying "I see you got the e-mail about the new haircut" while rubbing my head. They ALWAYS laugh and it is a great ice breaker and conversation starter. What "LINES" do you guys use when acknowledging other sly brothers. This "E-mail" line works great when I encounter sly cops, postal workers , grocers,etc. Really, anybody I run in to. TRY IT , you'll like the response you get.
